S6 Bluetooth problems since update

[AC Question]

I just purchased a 2017 Toyota Rav4 and the dealer set up my bluetooth. Everything has worked perfectly until I did the latest update. Since the update my bluetooth just randomly disconnects. It says call dropped and then a few seconds later it connects again. The call doesn't actually drop but the person on the other end can not hear me. Also when not on a call I can see that it loses connection randomly. Can anyone help?
